Predictors of perioperative morbidity and mortality in open abdominal aortic aneurysm repair.

•Suprarenal aortic cross clamping is associated with increased morbidity compared to infrarenal clamping.•Increased operative time is a risk factor for both perioperative morbidity and mortality.•Age is an independent predictor of mortality following open abdominal aortic aneurysm repair.•Perioperative hypothermia is a potentially modifiable risk factor for perioperative morbidity and mortality.
